. The invention relates to shingles, and particularly-to interlocking composition shingles, and has for its object to provide shingles of this character adapted to have an interlocking side' lap -5 with adjacent shingles whereby the nails holding the lower ends .completely protected against water being laterally driven in contact therewith.

A further object is to provide a shingle of this character having an absolute interlock with its adjacent shingles on a roof whereby movement of one shingle relative to the other is effectively prevented under all conditions.

A further object is to provide a shingle of this is character adapted to interlock with its adjacent shingles whereby the use of nails in laying a roof is reduced to a minimum, the interlock between the shingles holding the lower edges thereof securely to the roof.

With the above and other objects in view, the invention resides in .the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described, and claimed, it being understood that changes in the precise embodiment of the invention may bemade within the scope of what is claimed without departing from the spirit of the invention.

In the drawing: 1

Figure 1 is a plan view of a roof formed of these shingles.

Figure 2 is a fragmentary perspective view of two interlocked shingles bent to expose the under a side of the lower interlocked ends thereof.

Figure 3 is a plan view of the shingle.

Figure 4 is a plan view of a modified form of. the shingle.

. Figure 5 is a fragmentary perspective view similar to Figure 2 illustrating the interlock between shingles of the modified form shown in Figure 4.

Referring to the drawing, which illustrates the preferred embodiment of the invention, the numetal 9 designates a shingle of substantially square outline and of the composition type. At the left side of the shingle, at a point spaced from the lower edge thereof, is formed a cut 2 which may comprise a slit or a narrow cut and which I extends inwardly of the side of the shingle at an angle of approximately 45 degrees toward the lower edge thereof and terminates in spaced relation to the lower edge. At the lower end of the hingle is formed a cut 3 similar to cut 2 which nds inwardly of the shingle at an angle of :pproximately 45 degrees inthe direction of the ht edge of the shingle and terminates in spaced tion to said right edge. The inner ends of of said shingles to place are the cuts 2 and 3 extend in approximately the same horizontal plane of the shingle and are preferably equally spaced from the adjacent side edges of the shingle. Substantially triangular shaped flaps 4 and 5 are thus formed respectively n by the cuts 2 and 3 at the opposite sides of the lower end of the shingle. A nail hole 6 is formed substantially centrally of the flap 5.

The shingles are laid on a roof in courses, having the desired head lap I, and the adjacent shinles in each course are given aside lap 8 in the following manner: The flap 5 is nailed to the roof through the nail hole 6 to hold the lower right side of the shingle fixed to the roof. The shingle to the right is then disposed in horizontal alignment thereto and in overlapping relation to provide the side lap 8. The flap 4 of the overlapping shingle is then passed through the cut 3 of the first-laid shingle whereby it underlays said shingle inwardly and extending upwardly of the out n 3 therein, the side lap thus provided equaling the spacing of the lower end of cut 3 from the right edge of the shingle, or twice the distance between the inner end of cut 3 from the right edge of the shingle. When so laid the cuts 2 and a 3 of the overlapping and underlying shingles, respectively, are disposed at right angles'to each other and oblique relative to the edges of the shingles whereby they serve to lock adjacent shingles against relative longitudinal and lateral so displacement and hold the lower ends of each other effectively fiat on the roof to prevent curling, loosening and the like. It will be observed that the nail which holds the flap 5 of the shingle to the roof is covered by the flap 4 of the overlapping shingle, which in turn is overlapped by F the body of the underlying shingle, and therefore no water can possibly be drivenunder the overlapping flap 4 to the nails because of this underlapping of the end ofiiap 4 which overlaps 40 the flap 5 and nail. In all previous interlocking shingles the nailed portion or flap is provided with only one overlap member whose outer edges and ends are unsecured and which will therefore be liable to curl or raise to permit water running down the roof to pass under the overlapping flap to reach the nail, which is always lower than the remainder of the shingle due to the fact that it is driven into the roof and to which lower portion the water will naturally run it it gets under the overlapping flap; and therefore in these previous shingles no adequate protection for the nail against water is provided, whereas in the instant shingle the double overlap forms an effective seal for the nails.

to form a rectangular flap ll in the center of which a nail hole I! is formed.

The modified type 01 shingle is laid in the same mannerasthepreferredtypmtheflapllbeing nailedtotheroofandtheflaplloftheadjainterlock in the preferred construction. The only difference in this modified construction is in the relative angle of the cuts l l and I! when in interlocking relation, the angle in the modified construction somewhat facilitating the laying of the shingles.

The invention having been set forth, what is claimed as new and useful is:

A roof comprising courses of' overlapping shingles. each shingle having a pair angular slits therein to form corner flaps at the opposite lower corners thereof, one slit of each shingle extending angularly downwardly. from a side edge thereof and the other slit extending angularly upwardly from the lower edge of the shingle adjacent the opposite side edge thereof, the inner edges of said slits terminating in substantlally horizontal alignment, a fastening passing through the lower-edge-cut flap of each shingle, said fastened flap being overlapped by an adjacent shingle whose unfastened flap underlies the body of the underlapping shingle inwardly of said fastened flap to form a watertight seal for said fastened flap.
